LAUNDRY DRIER.

Application filed February 9, 1924. Serial No. 691,656.

To all whom it may concern:

Be it known that I, VILLIAM F. DELZER, ac-itizen of the United States,and resident of Milwaukee, in the county of Milwaukee 5 and State ofWisconsin, have invented certain new and useful Improvements in LaundryDriers, and I do hereby declare that the following is a full, clear,-and exact description thereof.

This invention relates to laundry driers. In laundry driers, asheretofore constructed, it has been found necessary to bring in freshair in addition to the products of combustion furnished by the burners,and to continuously remove the air from the drier. However, in driers aspreviously constructed, it frequently happened that the j incoming freshdid not become heated before it contacted with the clothes,- andconsequently the clothes were not subjected at all portions to heatedair, and therefore the drying was greatly retaI ded. I

This invention is designed to overcome the above noteddefeots, andobjects of such invention are to provide a laundry drier in which theincoming fresh air is caused to pass through the flame, or the highlyheated products of combustion, and to intim'a'tely' mix therewith priorto the time that U0 it reaches the clothes; to provide means whereby theheated air is caused to contact with the clothes and the air removedfrom the apparatus is merely that which has preportion of the heathasbeen extracted.

Further objects are to provide a simple construction adapted to fit astandard typeof laundry drier and to so organize the parts that themeans for bringing in the fresh air is heated from the burner and alsouniformly distributes the air throughout the length of the elongatedburner.

An embodiment of the invention is shown in the accompanying drawings. inwhich:

air, showing it associated with the burner.

and with the front plate of the drier.

5 The body of the laundry drier may be of viously been used and fromwhich themaj or Figural shows one form of laundry drier the usual formand comprises an upright casing 1 of sheet metal provided with one ormore slidably mounted doors carried in any suitable manner, as fromupper suspension members 3. The doors 2 may be formed in theconventional mannerand may carry a plurality of rods upon which theclothes are hung. This is the usual construction, and a. detailed exlanation and showing is not thought necessary, as the specificconstruction forms no portion ofthis'invention.

Below the doors a front plate 4 is positioned and is secured to the faceof the device in any suitable manner, bymea-ns of rivets 5, bolts, orother securing means. It

is provided with an aperture through which an elongated burner 6projects. burner a window 7 of mica, glass, or other transparentmaterial, is provided. Below the burners a triangular opening is formedand if desired may be provided with a plurality of vertical slats, orcross-bars 8,

as shown in Figures 1 and 8. This triangular opening is surrounded by aninwardly projecting triangular flange 9. A hollow triangular shapedmember 10 of sheet iron fits over the flange 9 and conforms thereto.This member 10, as may be seen from Figures 2 and i, extendssubstantially the entire length of the drier and isclosed at its rearend. It is provided with a plurality of regularly spaced apertures 11positioned on each side of the member through its slant ing walls andopening in close proximity to.

the burner. The burner 6 is provided with a plurality of apertures 12from which the flames are projected. These apertures in the burner aredirected slightly downwardly and outwardly, as shown in Figures 3 aud t.If desired, a strap 1% may surround the rear portion of the member 10and may engage the burner 6 to hold these parts in their correctrelativeposition, (see Fig. 2)

Above the The air, after it'has been used, is removed from'the apparatusby means of a pair of apertured pipes 13 located adjacent the bottom ofthe drier and upon opposite sides. These pipes lead out from the drierand are connected with a suitable flue.

The operation of the apparatus is as follows :-The burner, having beenlighted, will project a series of flames downwardly into proximity ofthe slanting walls of the member 10 and the heat radiated from suchflames will heat such member and consequently will preheat the airsupplied by the member. However, the fresh air drawn in through themember 10 is passed upwardly through the apertures 11 and is forced topass through the flame of the burner, or through the highly heatedproducts of combustion from such flame, before it is permitted to reachthe upper portion of the drier. Consequently, all of the fresh air isuniformly mixed with the products of combustion from the burner and theclothes are not subjected to any air which has not become properlyheated. The requisite circulation of air within the drier is maintainedby removing the used air from the device adj acent its lower sideportions by means of the pipes 13. Thus it will be seen a current ofuniformly heated air is continuously passed over the clothes and drawnfrom the apparatus without at any time subjecting the clothes to theaction of any streams of unheated air.

It will be further seen that the laundry drier forming the subjectmatter of this invention, can be readily produced by a slight alterationof the conventional type of drier and without requiring extensivechanges therein. In fact it is merely necessary to furnish the frontplate 4 with the burner and associated conduit 10 as a. unitarystructure, and to slip this unit into place, thereafter bolting, orotherwise securing the front plate in position.

I11 fact it is not necessary to secure the rear portion of the member10, although of course this is within the province of my invention, or,as will be seen from Figure 3, that the portion 10 may rest directlyupon the bottom 14 of the drier.

It will thus be seen that a highly efiicient laundry drier has beenprovided, which may be construct-ed in a simple and inexpensive manner,and which is so formed that the essential parts thereof may beassociated with conventional forms of driers without requiring expensivealterations therein.

Although the invention has been described in considerable detail, it isto be understood that it may be variously embodied, and is therefore tobe limited only as claimed.

I claim:-

1. In a laundry drier, the combination of an elongated casing, a burnerextending longitudinally thereof, means for conducting air from saidcasing, and an elongated fresh air inlet conduit located immediatelybelow said burner and adapted to distribute the air beneath said burnerin a substantially uniform manner from one end of said burner to theother, whereby the incoming fresh air is heated before it passes toother portions of the casing.

2. A laundry drier comprising an upstanding casing, an elongated burnerextend ing longitudinally and adjacent the lower portion thereof, anelongated fresh air inlet conduit having aplurality of apertures, saidconduit being positioned in close proximity to said burner and saidapertures being arranged beneath said burner from one end of said burnerto the other, and means for removing used air from adjacent the lowerside portions of said casin 3. A laundry drier comprising a verticalcasing which is adapted to receive the mate rial to be dried, a lowerplate adjacent one of the ends of said drier, an elongated burneextending from said plate longitudinally of said casing, and a hollowfresh air member opening outwardly through said plate and locatedimmediately below said burner, said member having a plurality ofapertures therethrough for distributing air below said burner, wherebythe incoming air is heated prior to reaching the material to be dried.

4. A laundry drier comprising an upstanding casing, a longitudinallyextended burner located in the lower portion of said casing and providedwith a plurality of downwardly and outwardly directed apertures, aninlet fresh air conduit located below said burner and having asubstantially triangular cross section with the apex thereof located inclose proximity to said burner,

said conduit having a plurality of apertures a 'anged in regular (orderadjacent said burner, a front plate for said casing secured to saidconduit and having an opening communicating therewith, and means withinsaid casing for conducting the used air from said casing, whereby freshair is drawn into said casing and is heated by the said burner prior toits passing to other portions of the apparatus.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of lVisconsin.
